With the method of FEA (finite element analysis), the distribution of temperature field in sense organ at different arrangements of hot-resistances and different accelerations, were obtained by building the three-dimensional model of airflow acceleration sensor’s sense organ.The results are asfollows: When the acceleration is not same, the temperature field distribution near the wires is different; The difference of temperature of 2 symmetry detection thermistors ΔT has also changed. If not beyond the measurement range, The more close to the heat flow center,the greater temperature difference between the two hot-resistances,and the greater output of voltage.
